Ptychography and related diffractive imaging methods

JM Rodenburg - Advances in imaging and electron physics, 2008 - Elsevier
Publisher Summary Ptychography is a nonholographic solution of the phase problem. It is a
method for calculating the phase relationships among different parts of a scattered wave …

Weed management in rice‐based cropping systems in Africa

J Rodenburg, DE Johnson - Advances in agronomy, 2009 - Elsevier
Weed competition is a major constraint in all the rice production systems in Africa. In addition
to the costs of weed control, weeds account for yield losses estimated to be at least 2.2 …

[HTML][HTML] Systems approaches to innovation in crop protection. A systematic literature review

M Schut, J Rodenburg, L Klerkx, A van Ast, L Bastiaans - Crop Protection, 2014 - Elsevier
The objective of this paper is to explore the extent to which systems approaches to innovation
are reflected in the crop protection literature and how such approaches are used. A …

An improved ptychographical phase retrieval algorithm for diffractive imaging

AM Maiden, JM Rodenburg - Ultramicroscopy, 2009 - Elsevier
… × J , where each of the J recorded diffraction patterns contain M × N pixels. The first constraint
set encloses valid solutions to Eq. (2), that is those exit-waves that can be factored into two …

Movable aperture lensless transmission microscopy: a novel phase retrieval algorithm

HML Faulkner, JM Rodenburg - Physical review letters, 2004 - APS
We propose an iterative phase retrieval method that uses a series of diffraction patterns,
measured only in intensity, to solve for both amplitude and phase of the image wave function …

Hard-x-ray lensless imaging of extended objects

JM Rodenburg, AC Hurst, AG Cullis, BR Dobson… - Physical review …, 2007 - APS
We demonstrate a hard-x-ray microscope that does not use a lens and is not limited to a
small field of view or an object of finite size. The method does not suffer any of the physical …

A phase retrieval algorithm for shifting illumination

JM Rodenburg, HML Faulkner - Applied physics letters, 2004 - pubs.aip.org
We propose a method of iterative phase retrieval that uses measured intensities in the diffraction
plane to solve the phase problem in a way that bypasses the problem of lens aberration…

Efficacy and safety of statin therapy in children with familial hypercholesterolemia: a randomized controlled trial

A Wiegman, BA Hutten, E De Groot, J Rodenburg… - Jama, 2004 - jamanetwork.com
ContextChildren with familial hypercholesterolemia have endothelial dysfunction and
increased carotid intima-media thickness (IMT), which herald the premature atherosclerotic …

Metronidazole plus amoxycillin in the treatment of Actinobacillus associated periodontitis

AJ Van Winkelhoff, JP Rodenburg… - Journal of clinical …, 1989 - Wiley Online Library
The potential use of an adjunctive therapy of metronidazole plus cillin for the subgingival
elimination of Actinobacillus actinomycetemcomitans in periodontitis patients was investigated. …

Arterial intima-media thickness in children heterozygous for familial hypercholesterolaemia

…, E De Groot, BA Hutten, J Rodenburg, J Gort… - The Lancet, 2004 - thelancet.com
… A Wiegman and J Rodenburg recruited and examined the children. BA Hutten was
responsible for statistics. E de Groot and J Gort were responsible for the ultrasound study. EJG …
